Os objetivos deste trabalho foram: (i) testar a eficiência do algoritmo de seleção de acasalamento (MS) em controlar o nível de endogamia e coascendência, além de aumentar os ganhos genéticos; (ii) incluir a variabilidade genética da futura progênie como componente de otimização na função objetiva de seleção de acasalamento usando dados de dois programas de melhoramento aquícolas; e (iii) comparar a MS com a seleção truncada (TS) e contribuição genética ótima (OCS), combinados com diferentes estratégias de acasalamentos para controlar a endogamia e manter os mesmo níveis de ganhos genéticos. Para os objetivos (i) e (ii), o total de 8.782 tilápias do Nilo (NT) de cinco gerações e 79.144 salmões coho (CS) de oito gerações foram utilizados para otimizar as funções objetivos e vinte gerações discretas foram simuladas para o objetivo (iii), considerando 50 famílias e 2.000 filhos por geração, e uma característica com herdabilidade igual a 0.30. As OFs foram otimizadas considerando a coascendência média dos pais, o mérito genético esperado, a endogamia da futura progênie para os objetivos (i) e (iii) e a variabilidade genética da futura progênie foi adicionada na OF para o objetivo (ii). Para o objetivo (i), a MS permitiu reduzir a endogamia em até 73% para tilápia do Nilo, em comparação com a seleção truncada e até 20% para o salmão coho, em comparação com o cenário real de acasalamento. No objetivo dois, a MS permitiu produzir progênie com maior (DP = 0.77 e 0.30 para NT e CS, respectivamente) ou menor (DP = 0.25 e 0.14 para NT e CS, respectivamente) dispersão dos valores genéticos, dependendo da função objetivo otimizada. A seleção de acasalamentos superou a seleção truncada e o cenário real de acasalamento e também foi possível alterar a variabilidade genética da futura progênie, quando esse componente foi considerado na OF utilizado os dados reais. Para os dados simulados, a MS teve melhor performance comparada com a TS e a OCS combinada com acasalamentos aleatórios. A curto-prazo, a MS foi mais eficiente do que a OCS combinada com os acasalamentos que minimizam a endogamia em controlar a endogamia sob o mesmo nível de ganho genético. Porém, a longo prazo os resultados entre as duas estratégias foram muito semelhantes. De forma geral, o algoritmo de seleção de acasalamentos foi eficiente e flexível em otimizar a função objetiva usando diferentes componentes, em diferentes aplicações práticas na aquicultura.
The aims of this work were: (i) test the efficiency of mate selection (MS) algorithm in controlling the inbreeding and coancestry level, as well, increase the genetic gain; (ii) include the genetic variability of the future progeny as component for the optimization of the MS objective function in two aquaculture real dataset; and (iii) compare MS among truncation selection (TS) and optimum contribution selection (OCS) scenarios combined to different mating strategies to assess the best method in controlling inbreeding and maintain the genetic gain, for aquaculture breeding using simulated dataset. For objective (i) and (ii), a total of 8,782 Nile tilapias (NT) from five generations and 79,144 coho salmon (CS) from eight generations were used to optimize the objective functions (OF) and twenty discrete generations were simulated for the objective (iii), considering 50 families and 2,000 offspring per generation, and a trait with heritability of 0.30. The OFs were optimized accounting to coancestry of parents, expected genetic merit and inbreeding of the future progeny for the objective (i) and (iii) and in addition the genetic variability of the future progeny was considered for the objective (ii). For the objective (i), the mate selection allowed reducing inbreeding up to 73% for NT, compared with truncation selection, and up to 20% for CS, compared with realized scenario. In the objective (ii), MS allowed producing animals with higher (SD = 0.77 and 0.30 for NT and CS, respectively) or lower (SD = 0.25 and 0.14 for NT and CS, respectively) dispersion of estimated breeding value, depending on the objective function optimized. For real data set the MS outperformed the real mates and truncation selection and in addition the genetic variability of the future progeny could be changed when this component was considered in the OF. For the simulated dataset, the MS outperformed the TS and OCS followed by random mating. In the short-term, MS was more efficient than OCS + inbreeding minimizing in controlling inbreeding under the same genetic gain. However, in the long-term, OCS and MS resulted in similar genetic progress and average inbreeding, under the same weight on coancestry. In general, the mate selection algorithm was efficient and flexible to optimize objective functions accounting for different components, under practical applications in aquaculture breeding.

Abstract:
While the existence of costs of mate choice is well accepted, the effects that these costs have on mating systems and the evolution of mate choice are controversial. The aim of this thesis is to explore a range of different types of costs, including costs of being choosy (using guppies, Poecilia reticulata) and costs of mating with attractive males (using house crickets, Acheta domesticus), and investigate how these costs influence female mating behaviour, sexual selection on males and the evolution of mate choice. I use a range of experimental techniques to investigate these questions including: comparisons of feral populations of guppies (Chapter Two), laboratory experiments that manipulate the social (sex ratio, density; Chapters Three and Four) and physical (water current; Chapter Five) environment in which guppies live, genetic paternity analysis and multivariate selection analysis (Chapter Four). I also conduct longitudinal studies of house crickets that estimate the net fitness consequences (Chapter Six) and indirect effects (Chapter Six and Seven) of mating with attractive males. My results demonstrate that the physical and social environment of individuals are important in determining the costliness of both sexual display and mate choice, and thus influence the mating behaviour of males and females. These differences in mating behaviour are often thought to lead to differences in sexual selection on males. My study of the effects of operational sex ratio and density on multivariate sexual selection, however, indicates that differences in behaviour may not necessarily translate into differences in selection. In contrast to predictions of recent theory, my results also indicate that although there are many costs to being choosy and to mating with attractive males, these may be outweighed by indirect benefits. Hence, despite direct costs of choice, mate choice may evolve via indirect benefits to females. Indirect benefits that are often neglected in sexual selection studies, that I show to be important in determining the net fitness of mating with attractive males, include the attractiveness of sons and the mate choice decisions of daughters. These results highlight the importance of examining the consequences of mate choice over multiple generations.

Abstract:
Mate selection has garnered much attention in the existing literature. However, most mate selection research has reviewed mate selection preferences and criteria individually. In this study, the researcher attempted to illustrate mate selection as an interactive process in which individuals are affected by external influences, and their mate selection criteria are influenced by their self-appraisals and their perceptions of others' mate selection criteria. Two studies were conducted. Study 1 was based on social exchange theory, sexual strategies theory, and social context frameworks, and used multiple-group structural equation modeling to describe the relationships among gender, receptivity to external influences on mate selection, self-perceived relative mate selection position, and relative mate selection demand, between Chinese and American never-married heterosexual adults. The results indicated that the model fit the data well. Self-perceived relative mate selection position and relative mate selection demand were negatively correlated. Women had a higher relative mate selection demand than men did. Self-perceived relative mate selection position fully mediated the effect of receptivity to external influences on relative mate selection, though the indirect effect was not significant. Path values did not differ between Chinese participants and American participants. Study 2 confirmed that the model fit the data well and replicated all significant correlations among latent variables found in Study 1. Additionally, Study 2 found that receptivity to external influences and self-perceived relative mate selection position were positively correlated, and that receptivity to external influences had a negative indirect effect on relative mate selection demand, fully mediated by relative mate selection position. Lastly, the researcher discussed findings, implications, strengths, limitations, and future directions of the present study.

Abstract:
Abstract This thesis deals with factors affecting mate choice as well as with genetic variation in male courtship song in Drosophila montana. Males, which produced song with a high carrier frequency, were found to court females, and also to succeed in their courtship more often than the males producing low frequency song. Male mating success correlated with the carrier frequency of his song recorded after, but not before, an "artificial winter", which suggests that a sexually selected male trait is sensitive to environmental factors. A high carrier frequency of male courtship song correlated positively with the survival rate of the male's progeny from egg to adulthood (indirect benefit for the female), but not with the fecundity of his mating partner (no direct benefit for the female). The heritabilities and the amount of additive and residual variation in male courtship song characters were measured in two populations using father-son regression and sib analysis. The songs of the males from one of these populations were analysed for a second time after the cold treatment. Most heritability values were insignificant, largely due to high residual variation. During the cold treatment, the additive variation increased and the residual variation decreased in almost all song traits. Increased variation in sexually selected traits may help the females to exercise selection between the males during the mating season of the flies in the wild in spring. This, and the fact that male song gives the female information about the male's condition/genetic quality suggests that in this species the evolution of female preferences for male song characters could have evolved through condition-dependent viability selection as postulated by "good genes" models. Variation and inbreeding depression/heterosis were studied in traits associated with fly reproduction using inbred D. montana strains. Songs, hydrocarbons and some behavioural traits of the flies varied significantly between strains. The strain of both sexes affected female egg-laying, and the female strain, also, the survival rate of the flies' progeny, in different intra- and interspecific combinations. Heterosis was found in the mating propensity of the flies and in the carrier frequency of the male song. Diallel analysis revealed unidirectional dominance towards higher carrier frequency. This direction is the same as the direction of sexual selection exercised by the females of this species suggesting that sexual selection could be a driving force in evolution of this song trait.

Abstract:
With the increased exposure to Western cultures and the transition towards modernization, Chinese society has experienced substantial social change, which has influenced marital relationships. Although recent research has documented contemporary patterns of marital interaction, less is known about what Chinese adults consider to be an ideal marital partner and what their parent' roles play in the mate selection process. What do contemporary Chinese adults value in a partner? How much parental influence is involved in choosing an ideal marital partner? These questions were addressed by conducting six focus groups in Taipei, Taiwan. The focus groups included a total of 51 participants (male = 25; female = 26) and included separate groups for middle-aged married men, middle-aged married women, younger married men, younger married women, never-married young adult men, and never-married young adult women. The results from qualitative analysis indicated three major themes in an ideal partner: family-of-origin (e.g., similar family background, good relationship with in-laws), personal qualities (e.g., financially stable, responsible), and relationship qualities (e.g., getting along, communicating well, mutual respect, gender equality). These results indicate that contemporary Chinese adults value a combination of traditional Chinese (e.g., similar family background) and Western (e.g. good communication) values. When it comes to parental approval on their marriage, most younger participants reported that they would marry a person despite their parents' disapproval, although many indicated that they would want their parents' approval because it would increase family harmony. The older participants, on the other hand, were more likely to still favor parents having significant influence on who their children marry. Overall, the young Chinese participants showed greater incorporation of Western values than the older participants. These findings suggest that modern Chinese society is being increasingly influenced by individualistic Western values.

Abstract:
The overall obejctive of the research project was to enhance the intrinsic biological control potential of entomopathogenic nematodes through genetic manipulation. We have chosen heat and desiccation tolerance as prime traits to be enhanced in order to increase the overall efficacy of these nematodes against insect pests under harsh conditions. Initially, we used mutagenesis and selection approaches to enhance these traits. In the mutagenesis experiments several morphological mutants of Heterorhabditis bacteriophora HP88 were isolated and characterized phenotypically and genetically. Infective juveniles of H. bacteriophora HP88 were subjected to heat and desiccation selection regimes for several generations. Small increase was recorded, after 4 and 6 rearing cycles for both traits. However, in both selection regimes a significant deterioration in the reproductive capability of the nematodes was observed. In a screen of new nematode populations, from arid regions in Israel, a heat tolerant (IS5 strain) and desiccation tolerant (IS6 strain) were isolated. Both strains were taxonomically identified and their beneficial characteristics (environmental tolerance, insecticidal virulence and reproduction) were determined. We further investigated the stability of the enhanced heat tolerance trait in, and the storage capacity of, the newly discovered IS5 strain. Genetic studies demonstrated that the heat tolerance of the IS5 strain is genetically based and is dominant. The trait for heat tolerance was transferred from the IS5 strain to the HP88 strain of H. bacteriophora. The transfer was accomplished by allowing the heat tolerant strain (IS5) to mate with the commercial strain (HP88). The hybrid nature of the progeny was confirmed using a recessive marker mutant of the HP88 strain (H-dpy-2). We have used (RAPD-PCR) to compare genetic variation in the IS5 and the HP88 strains of H. baceriophora. The results indicated that genetic variation in the HP88 was significantly less than in the IS5 strain which was recently isolated from the field. The new IS5 strain may be used as an effective biological control agent in warm environments. In addition, IS5 can be used as a genetic source for cross-hybridization with other H. bacteriophora strains.

Abstract:
The article considers online tools for creating tests, which should be used when teaching mathematics in both higher education and general secondary education. Among the variety of online means of creating tests by the method of expert evaluation, three were identified, which allow conducting various tests both in the classroom and remotely, which are free and do not require special conditions for their use and which work on smartphones. The advantages and disadvantages of three online tools for creating tests Kahoot!, Quizizz, Classtime are analyzed, and a comparative description of the selected tools is given. Criteria for the selection of such tools were identified – functional-didactic and organizational. The following indicators belong to the functional-didactic: the presence of different types of questions, including open-ended; use of formulas, both in questions and in answers; use of pictures, both in questions and in answers; no restrictions on the length of questions and answers; instant receipt of results by the teacher, their evaluation and analysis; instant receipt of results by the respondent; to the organizational: the availability of a free version; no need to install the program; ease of use – characterizes the convenience and clarity of the interface for creating tests and their use; possibility of testing in online and offline mode; time limits, both for a single question and the whole test; random order of questions/answer options; instant demonstration of the correct answer to the respondent. With the help of expert evaluation, it was found that according to these criteria, Quizizz is the most appropriate for testing.

Dunham, Rex A., Boaz Moav, Thomas Chen, and Benzion Cavari. Expression and Inheritance of Growth Hormone Gene Constructs and Selective Breeding of Transgenic Farmed Fish. United States Department of Agriculture, August 1994. http://dx.doi.org/10.32747/1994.7568774.bard.

Abstract:
Objectives: To accomplish stable expression, inheritance of transgenes and growth improvement in transgenic channel catfish, Ictalurus punctatus, and common carp, Cyprinus carpio, containing growth hormone (GH) genes, develop transgenic fish with all fish constructs, determine the relationships between copy number, expression and growth, determine the combined affect of selective breeding and gene transfer and assess environmental risk of transgenic fish. To develop mechanisms of triploidization for transgenic carp. Results: Performance of transgenic channel catfish was made uniform by selection. Growth of channel catfish and common carp was improved 40-50% more by combining gene transfer of GH genes with selection and crossbreeding than with either selection of crossbreeding. Growth improvement of transgenic catfish was not strongly correlated with copy number and expression levels. Progress was made in producting triploid transgenic common carp. Insertion of salmonid GH gene did not alter reproductive performance in channel catfish. Transgenic channel catfish grew no faster than controls when they had to forage on natural food and transgenic individuals were slightly more vulnerable to predation indicating that fitness of transgenic individuals in natural conditions is less than or equal to non-transgenic channel catfish. Contribution to Agriculture: These experiments are the first to demonstrate that transgenic fish can increase aquaculture production in the aquaculture production in the aquaculture environment. This research also demonstrated that maximum benefit of gene transfer in farmed fish is attained when combined with traditional selective breeding.

Sutipatanasomboon, Arpaporn. Petri Dishes with Agar: How to Make Agar Plates. ConductScience, June 2022. http://dx.doi.org/10.55157/cs20220627.

Full text
Abstract:
Petri dishes and agar form the foundation of the culture plate technique pioneered by Robert Koch, facilitating the cultivation and study of microorganisms. Agar, derived from red seaweed, solidifies into a transparent medium for microbial growth. Agar plates are classified as nonselective, allowing general growth, and selective, inhibiting specific microbes. Petri dishes, with a dish and lid, provide containers for agar, supporting microbial growth. This technique has revolutionized microbiological research, enabling advances in fields like bacteriology, mycology, infectious diseases, and biotechnology.

Navarro, Lucas. Entrepreneurship Policy and Firm Performance: Chile's CORFO Seed Capital Program. Inter-American Development Bank, August 2014. http://dx.doi.org/10.18235/0008445.

Abstract:
This paper uses administrative data from projects for which an application was made to CORFO's (Chile's main development agency) Seed Capital Program (SCP) during the 2008-12 period. This paper analyzes the impact of the program, which is a subsidy provided to new, innovative firms, on Start, Growth, and Survival. The projects are supported by sponsors in the application process. Results of our analysis indicate that, controlling for observed characteristics, projects that received the subsidy had a 9.5 percentage point higher probability of starting to sell. Among created firms, subsidized (Treated) firms showed a 17 percentage point higher probability of significant Growth (in sales) and a similar effect on Survival. The analysis also examined a change in the program rules in 2011, whereby sponsors were paid based on performance instead of fixed fees, as it was before 2011. For projects affected by the policy change, results indicate no overall association of the program with the probability of Start and a positive correlation with Growth and Survival. These results could be a consequence of sponsors making better project selections for funding. The change in rules means that the program contributes more to the Growth and Survival of new firms than to their Start, which would take place anyway. The data available for this study did not make it possible to control for potential selection biases, and thus the results need to be viewed with caution, and data collection standards need to improve to help identify the true effect of this type of program.

Muñoz, Juan Sebastián. Re-estimating the Gender Gap in Colombian Academic Performance. Inter-American Development Bank, January 2014. http://dx.doi.org/10.18235/0011529.

Abstract:
This paper presents evidence of the relationship between the disparity in the academic performance of boys and girls in Colombia and the country's excessively high school dropout rates. By using the OLS and trimming for bounds techniques, and based on data derived from the PISA 2009 database, the presented findings show that the vast majority of this gender-related performance gap is explained by selection problems in the group of low-skilled and poor male students. In particular, the high dropout rate overestimates male performance means, creating a selection bias in the regular OLS estimation. In order to overcome this issue, unobservable male students are simulated and bounding procedures used. The results of this analysis suggest that low-income men are vulnerable to dropping out of school in the country, which leads to overestimating the actual performance levels of Colombian men.
